During the period when they are producing sperm, male sea lampreys (Petromyzon marinus L.) release a sex pheromone 7alpha, 12alpha, 24-trihydroxy-5alpha-cholan-3-one-24-sulfate (3 keto-petromyzonol… (More)
Although four different primary olfactory pathways have been described in tetrapod vertebrates, polymorphic olfactory sensory neurons comingle in the olfactory epithelium and project axons into… (More)
The morphological and functional differentiation of the olfactory receptor cells were investigated in developing rainbow trout (Salmo gairdneri) embryos by means of light and electron (transmission… (More)
Previous studies of the round goby (Neogobius melanostomus Pallas, 1814), an invasive fish species in the Laurentian Great Lakes of North America, have shown that this species has the ability to both… (More)
The motor deficits associated with Parkinson's disease may be ameliorated by intrastriatal placement of dopamine-secreting cells in a polymer capsule. Water soluble polyelectrolytes were utilized for… (More)
1. Gustatory responses to amino acids and derivatives obtained from the palatine nerve (VIIth cranial nerve) of rainbow trout (Salmogairdneri) were studied. 2. The response to an amino acid was… (More)
Chromaffin cells have been shown to release a combination of pain-reducing neuroactive compounds including catecholamines and opioid peptides. The allogeneic transplantation of chromaffin cells in… (More)
We conclude that spermiating male sea lamprey release a large amount of 7α,12α,24-trihydroxy-5α-cholan-3-one 24-sulfate via their gills. We suggest that this compound is used to signal the location… (More)
Congenital laryngeal saccular cysts of the newborn frequently cause severe dyspnea and upper respiratory tract obstruction. When confronted with this emergency situation necessary therapeutic action… (More)
GABA is a putative inhibitory neurotransmitter in adult mammalian visual cortex but also has been implicated as playing a crucial role in cortical information processing during development. In order… (More)
